The above conclusions seem to ])oint to the fact that a larij,e animal 

 is a more economical producer of meat than a small one of the same age, 

 especially when considered in conjunction with Voit's(77) results which 

 confirmed Rubner's theory that the amount of energy required by a 

 young animal when calculated in relation to unit of body surface is the 

 same as that of an adult, the younger and smaller animals having a 

 larger surface per kilo body weight than adult and larger animals.

My thanks are due to Mr E. J. Powell, Secretary of the Smithfield 

 Club, who has very kindly supplied me with records of the Shows, to 

 Mr Charles Bone of the Central Meat Markets, London, who has given 

 me information on the methods of slaughter and dressing adopted, and 

 lastly to Dr F. H. A. Marshall, F.R.S. who has given me the benefit of 

 his advice in the prej)aration of this paper.
